HYDROMOTOR.

Specification of Letters Patent.

Patented June 16, 1908.

Application filed April 2, 1906. Serial No. 309,300.

T 0 all whom it may concern:

Be it known that I, ANTON GRAF, of New bury, in the county of Essex andState of Massachusetts, have invented certain new and usefulImprovements in Hydromotors, of which the following is a specification.

My invention relates to new and useful imprlovements in the propulsionof boats or vesse s.

My invention consists of certain novel features hereinafter describedand particularly pointed out in the claims.

In the accompanying drawings which illustrate a construction embodyingmy invention,'Figure 1 is a top plan view of a boat containing myimprovements arranged in duplex. Fig. 2 is a side elevation of the same.Fig. 3 is a detail side elevation of the l'iydromotor and cooperatingparts, with the arrows showing the direction of the flow of the waterand with certain valves opened and others closed. Fig. 4 is a similarview to Fig. 3 and showing the position of the valves and the flow ofthe water indicated by the arrows, when the mechanism is operated toreverse the motion of the boat. F ig. 5-is a detailed side view of oneof the valves with the mechanism for operating the same to open andclose it. Fig. 6 is a side view of the hydromotor. Fig. 7 is atransverse vertical central section through the hydromotor on the lineYY (Fig. 6) looking in the direction of the arrow with parts in fulllines. Fig. 8 is a longitudinal sectional view on the line X X Fig. 6looking in the direction of the arrow and with the parts in full lines.Figs. 9 and 10 are respectively side and perspective views of the wheelhereinafter described.

Like letters of reference refer to like parts throughout the severalviews.

ithin the boat A, shown in dotted lines, is located a boiler B, of anysuitable construction and from said boiler leads a steam pipe Ccontrolled by the valve O and forming an injector or inspirator O withinthe injector chamber D. To the bottom of the chamber D is connected apipe E which is connected by aT joint to the pipe E opening at E to thewater around the front of the boat. Hand operated valve O controls theflow of steam to the injector O Connected to the chamber D is a pipe Owhich is bolted or otherwise secured to the duct F of the hydromotor,which. consists of two exterior plates F joined together by suitablebolts as shown. At the center these plates have each an inwardly turnedcircular flange f (see Figs. 7 and 8) and passing through these flangesis the shaft f having bearings and f extending outwardly from theflanges f and on said bearings are screw threaded suitable stuffingboxes f Mounted fast on said shaft f is .a spider f with blades f 2forming the wheel of the hydro motor. on each of said blades are locatedfour plates f capable of movement and guided in their movements by thepins f located in suitable slots in said plates Between the edges ofsaid plates are located springs f adapted to force said platesautomatically outwardly to make a closer fit within the plates F toprevent the escape of water past said blades. WVhile I have shown theseadjustable plates yet in practice they may or may not be used asdesired.

The inner edges of the plates f extend as shown at f beyond the spider fand over the edges of the flanges f, as shown in Figs. 7 and 8. Theoutlet f 7 from the hydromotor (Figs. 3, 4 and 6) connects with the pipeF which communicates by the T-joint F with the exhaust pipe F The pipe Eis controlled by a suitable gate valve E which moves up and down, ashereinafter described. It is connected at its uper end by a slottedconnection to the lever I carried fast on the shaft II. On the saidshaft supported by the brackets II is a gear segment H which meshes withthe rack H on the rod H This rod I-I extends rearwardly and is providedat its rear with a suitably mounted lever H". On said rod H is mountedthe bell crank J pivoted on to the standard J and to said bell crank isconnected a rodK moving in the guide J on said support J, and to saidrod K is secured fast the rod K likewise secured fast to the stem of thevalve F in the pipe O As shown in Fig. 3, the valves E and F" are raisedthereby opening the pipes E and C In the pipe F which communicates withthe pipe O through the connections previously described is a valve F thestem of which is connected to the lever II fast on the shaft H on whichis also fixed another gear segment II which meshes with another rack Hon the rod IF. As shown in Fig. 3, the valve F is open as are also thevalves E and F.

With the parts described and in the positions shown in Figs. 2 and 3,the boat is started forward by opening the valve C which allows steamfrom the boiler B to pass into the injector chamber D, which steaminduces a suction of water from the front of the boat through the pipe Einto the pipes E up into the injector chamber D through the pipe C pastthe valve F whichis open, into the duct F and impacts against the bladesf of the wheel, thereby rotating said wheel, and passes out from thehydromotor through the outlet y into the pipe F, then into the pipe Fpast the open valve F, into the water at the rear of the boat, asindicated by arrows (Fig. 3). In the pipe D is the valve D, which isclosed while the steam and water are passing through the pipe C to thehydro motor. The closing of this valve prevents the steam and water frompassing through the pipes D and F while the valve F is open. In thisarrangement, it will be seen the water is drawn by suction away from thefront of the boat and forced out at the rear of the boat, the action ofwhich is to draw the boat ahead at the bow and force it ahead at thestern.

On the shafts f (Fig. 1) are mounted the bevel gears a which mesh withbevel gears b on the shafts 0 supported by the brackets d and on theends of said shafts are the propellers e. The rotation of the wheelwithin the plates F due to the impact of the water and steam, causes arotation of the shaft f which is communicated as above described to thepropellers e.

To back the boat when standing still or to reverse the boat when goingahead, the operator takes hold of the lever H and pulls the samerearward (Fig. 4) which causes the rod H to move the rear segments Hrearward, thereby opening the valve E connected to the lever H fast onthe shaft H and to close the valve F connected to the arm I-I fast onthe shaft II and to close the valve F by means of the bell crank J andconnections previously described and further to close the valve Econnected to the lever I'I fast on the shaft H and to open the valve Gconnected to the lever H fast on to said shaft H. The parts being movedas just described, and the valve C being open, the injector C" inducessuction of water from the stern through the pipe E (Fig. 41) to thepoint and up through the pipe E into the injector chamber D, through thepipe C to the joint C (the valve F being closed) down through the pipe D(the valve D being open) to the pipe D to the joint F (valve F beingclosed) up through the pipe F into the hydromotor, turning the wheel tothe left and up and out through the duct F to the joint D and downthrough the pipe G through the joint D and out through the pipe G,discharging through the end G thereof in the front of the boat. Thisreversal of the propeller mechanism aided by the suction at the rear ofthe boat and the discharge at the front of the boat moves the boatrearwardly. The course of the water and steam is indicated by arrows inFig. 4 in the backing or in reversing the boat for backward movement.

The valve F controls the flow of steam pressure and water to the motorin that on the forward movement of the boat, said valve F being open,steam pressure and water pass into the motor through the duct from thepipe C while on the back or reverse movement of the boat, the valve Fbeing closed,

steam pressure and water pass down the pipe D into the pipe D up throughthe pipe F 4 into the motor out through the duct F to the joint D anddown through the pipe G2 and out through the pipe G.

While I have shown in Fig. 1 a hydromotor and its connecting ductsarranged in duplex, yet it will be understood that one hydromotor withits connecting ducts or any number of motors with their connecting ductsmay be used.

In another application Serial No. 265,849 filed June 19, 1905, I havedescribed and claimed the hydromotor without limiting it to a boat orvessel.
